TODO: Look into what's needed for host mode; is switching the dr_mode enough (with a powered hub)? how will power delivery from the port work? can we make it dual role already? |
Display
|
TODO: Figure out what's required to draw images on virtual terminal (with simplefb; X.org already seems to render an Xfce4 desktop just fine, does Wayland work? |
I2C
|
TODO: Check out NFC in userspace with neard, rfkill node in sysfs at least is registered already :) |
SPI
|
TODO: Test with linux-tools-spi on Volla Phone 22 (volla-mimameid) after adding nodes for fingerprint sensor under spi2! |
Mainline fork
There is a mainline kernel fork on GitLab @ mtk-mainline/mt6768/linux where development is currently (2022-11-03 / v6.1-rc3) not active.
Most information for MediaTek Helio P23 (MT6763) is also applicable here, most of that should be consolidated to a generic MediaTek mainlining page...
